TO ALL WHOM IT MAY CONCERN: r

Be it known that I, THOMAS'J. SLOAN, of New York, of New York county, in the State of New York, have invented certainnew and useful Improvements in Apparatus for Opening and Closing Window-Blinds andI do hereby declare thatthe following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this application. t I

' My invention relates to certain new and useful improvements in devices for opening and closing and-locking" in either position outsidej-window-blinds.

Previous to my invention, several d evices'or mechanisms have been suggested and employed to accomplish the ends-of my present invention, and Letters Patent have been granted to me for such device's.

The object of my present invention is to afford a simple, durable, and economic mechanism or device, by means of which any outside blind may be readily opened and closed, and fastened in either position, by 1, imply turning a handle, arranged on the inner side of the window-frame and also to so adapt and apply such a device that vthe blindcan. be unhung-with the same facility'as ifmonnted on ordinary hinges, and without in'the least interfering with the operations of said device; andte' these ends my invention consists in the employment, in com- 'bination with the toothed-hinge sector, driving-sector, and rotary shaft or rod, of a catch or bolt for retaining the driving-sector in different positions, andoperated by a cam and'spring, all as hereinafter morc fully described. And my invention further consists in the employment, inconnection with the hinge-scctor and its support, of a swinging pendant, so arranged over the'hinge-sector that, when in its normal position,.it securely retains the mind on its bearings (or hinges,) and wheuturned up will permit the ready removal of the blind, as will be presently more fully described.

To enable those skilled in the art to make and use my invention, I will proceed to describe it more-fully, referring by letters to the accompanying drawings, making part of my applicatiomiand in which- Figure 'l-is an edge view of a windowframe and shutter, (the latter open,) hung thereto with my improved 1 opening and closing-hinge device.

Figure 2 is an outside face view of thesame, showing the blind closed, and

Figure 3 is section at the line a a, fig. 1. v

In the several figuresthe same letters denote the same part of the apparatus.

A is'the window-frame, and B an ordinary outside blind or shutter, which is hung near its upper end to the window-frame by meansjof the ordinary hinge, O, and near its lower end by one of my improved opening and closing-hinge devices or mechanisms, which consists of a metallic stand, D, secured to the outside of the windowframe, and carrying the working parts and a' toothed-hinge scctor arm, E, secured "to the shutter or blind, as

clearly shown. Y

The stand isformed with an arm, e, which serves as the supporting-shank of hinge-sector f, and also with another arm, 9, in theextremity of. which is arranged a pendant, F, the operation and advantage of which will be presently explained. r I

. H isthe rotary shaft, which'passe's through the windowframe in suitable bearings, the outerend taking a bearing in the arm e, and the inner end being provided with a handle, I, by means of which it is turned. On this shaft H is hung loosely the driving-sector gear, K, the hub of which has cut in. it a longitudinal slot, 2' through-which protrudes the pin Z from shaft H, in su'ch a manner that when said shaft is turned in either direc tion, saidpin will act as 'a'clutch and carry the sector-gear and the hub of said sector-gear is also made with shoulders at m, which come against the catch-barn, when down,-.as will be presently explained.

O is a cam, secured on shaft H, and so formed and arranged as to lift and hold up the catch-bar n. This bar at is arranged to slide vertically in cars or projecting lugs, pp, and is eontinnaIIypressed down by-a spiral spring, S.

r The pendant F retains the blind on its hinges against any tendency to lift off, but is hung on a pivot, so

that itmay be turned or swing upward, (as indicated by the red lines, fig. 1,) to permit the blind to be lifted off its hinges, in the usual manner, for any desired purpose.

The operation of the several parts, already alluded to may be th'us explained:

Supposing the shutter to happened, (as seen at fig. 1,) itis retained in this position 'by the catch-bar m which, being down past one of the shoulders m of the hub of gear K, prevents the said gear from turning, and thereby locks the shutter back. When the shutter is-to be closed, the handle-I is taken hold'of and the shaft H rotated. By the rotation of said shaft, the earn 0 isturned and'eaused-to lift the catch-barn, thereby releasing the hub of gear K. As soon as this release is effected, the pin Z, which turns with shaftH, comes against and carries along with it the hub of gear K, and the latter driving the gearf, effects the turning of tho blind on its pivots or hinges and closes it. As soon as the blind is quite closed, the spring-catch n shoots down post another shoulder 'm, and locks the blind in its closed positich- When it is desired to reopen the blind, it is only necessary to rotate the shaft H in the opposite direction, when the locking-catch will be first raised, and the sector and gear then turned in the'opposite direetionsto those just alluded to.

Having explained the construction and operation of my improved shutter-mechanism, so that one skilled in the art can make and use it, what I claim as new, and desire to secure by Letters Patent, isp The employment, in combination with the gears K, j, and shaft H, of the retaining-catch barn, and a cam. O, for lifting the same, the whole arranged to operate substantially as described for the purpose set forth.

I also claim the employment, in combination with the hinge-sectorf and stand D, of a swinging or movable retaining-pendant, F, arranged to operate as described for the purpose set forth.

In testimonywhereof, I have hereunto set my hand and seal, this 18th day of December, 1867 'THOS. J. SLOAN. 1,. 5.
